Holo-krome 03074 Oversized Dowel Pin Alloy Steel Grade 4000

Product Description

The HOLO-KROME 03074 is a military specification oversized dowel pin manufactured from Grade 4000 alloy steel with a black luster finish. Measuring 0.5 inches in diameter and 1.5 inches in overall length, this pin is produced to ASME B18.8.2 standards and features one beveled end and one rounded end. The oversized diameter tolerance of 0.0010 inches provides a controlled press fit for precision alignment applications. It is commonly installed by machinists, toolmakers, and maintenance technicians in assemblies requiring tight positional accuracy and repeatable part location.

This dowel pin suits industrial and military-grade alignment applications where standard pins are insufficient due to worn or enlarged holes. The oversized design allows it to restore proper fit in existing bored holes without full rework. Typical applications include fixture alignment, jig construction, machinery assembly, and precision tooling applications that must meet military or ASME fastener standards.

Key Features

• Manufactured to ASME B18.8.2 military specification standard
• Grade 4000 alloy steel construction for high strength and durability
• Black luster finish for corrosion resistance in industrial environments
• One beveled end and one rounded end for guided installation
• Oversized diameter tolerance of 0.0010 inches for press-fit alignment in worn bores
• Compact at 0.082 pounds per piece — lightweight for high-volume assembly work

Compatibility

Designed as an ASME B18.8.2 compliant oversized replacement dowel pin for precision alignment applications in industrial, tooling, and military-grade assemblies requiring a 0.5-inch nominal bore diameter.

Installation Notes

Dowel pins of this type are typically installed by machinists or maintenance technicians using an arbor press or mallet with a suitable driver. Always verify bore diameter and surface condition before pressing — oversized pins require a clean, properly sized hole for correct interference fit. Shut down and de-energize or de-pressurize all associated machinery before pin removal or installation. Avoid driving pins with direct hammer blows to the finish face to prevent deformation.
